ISO 18593:2018 (the latest version) is titled: "Microbiology of the food chain — Horizontal methods for surface sampling techniques using contact plates and swabs."
Unlike vertical standards that focus on testing the food itself (e.g., a sample of minced meat), ISO 18593 focuses on the environment. It standardizes how to physically transfer microorganisms from a solid surface (stainless steel, plastic, rubber) onto a culture medium or into a diluent for further analysis.
A horizontal method means the standard can be applied across the entire food chain: Cons: The standard is detailed because surface sampling
Best for: Flat, smooth, non-absorbent surfaces (stainless steel, glass, sealed concrete).
How it works:
Pros:
Cons:
The standard is detailed because surface sampling is error-prone. Here are three frequent mistakes the standard addresses:
| Problem | ISO 18593 Solution | | :--- | :--- | | Varying pressure | Recommends using a constant-pressure device (spring-loaded) for contact plates. | | Incomplete recovery | Mandates a specific swabbing pattern and rotation to dislodge adherent cells. | | Residual disinfectants | Requires the use of neutralizers (e.g., lecithin, polysorbate 80) in the agar or broth. | unknown file repositories) are often outdated
